To all whom it may concern:

Be it known that 1, JOHN H. Rose, a citizen of the United States, residing at Dayton, inthe county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Oscillating W'ater-Motors, of which the following is a specification, reference being had therein to way valve arranged to simultaneously con-i trol both the ingress and egress of the water and having its valve stem extending through one of thecylinder heads and having mechanism mounted on said cylinder head and controlled by the rotation o'fthe motor shaft for actuatlng said valve stein.

In the accompanying drawings, Figure, 1 is a topplan view of a motor embodying my invention, with the cap removed; Fig, 2 is a vertical sectional view, taken centrallythrough the'same; Fig. 3 is a detail view of the valve and its act-uatin finger; and Fig. 4 is a transverse sectiona view, taken through the abutment and thevalve on the linewmofFigfl.

In these drawings I have, illustratedone embodiment of my invention and have shown the same as comprising a casing which is preferabl cast in two here shown the oy indrical portion 1 of. the casing-has the upper cylinder head 2 permanently secured thereto and is provided with a radially arrangedabutment 3, both the abutment and the cylinder head being prefcrably cast integralwith the cylindrical portion of the casing. The-cylindrical ortion 1 has at its lower edge'an'annularf ange 4- to, which is secured the lower cylinder head:

5. This lower cylinder hea d,ns here shown, comprises a fiat, circularplate of a diameter substantially equal to thediameter of the annular flange 4 and secured thereto by '7 being arran ed between the flange and t e lower cylin er head to prevent the leakage of the pieces As '25 arran ed betweenthe stops water between these members. The lower cylinder'head 5 has mounted thereon and preferably cast inte a1 therewith an inlet pipe 8 having a nipp e 9, by means of which it may beoonnected to the usual supply pipe and communicating with an inlet opening 10 in the abutment 3, which-inlet o ening, in turn, communicates with a valve 0 amber 11 in the abutment. A nipple 12 is secured to and preferably cast with the cylindrical portion 1 of the casing and comprises an exhaust conduit which is also in communication with the valve chamber 11 This valve chamber is in communication with the chamber formedwithin the interior of the motor casing on each side of the abutment, and, to this end, is provided with ports 13 and '14 extending through the opposite sides of the abutment. A turn-plug valve 15 is mounted in the valve chamber 11 andhas its side" portions cut=away to form ports 16, which ports are so arrangedthat, when the valve member is in one position, the inlet 10 will be connected with the port 13 and the exhaust 12 with theport 14. When the position of the valve member is reversed the in- 'and loweroylinder heads of the casing and has ri idly secured thereto a piston 18 which ts snugly within the chamber formed within-the casm The upper cylinder head 2 is provided with a boss 19 which forms a part of the bear-in for the motor shaftand which is connect diately above the abutment 3 and having two steps 22 and 23 extendin upwardly therefrom -on--'o osite sides 0 the radial center thereof. hestem'24 of the valve 15 extends-through the uppercylinder head 2 and the boss 21 and has securedthereto afinger 22 and 23 and connects to the valve stem in such a manner that, when it is in edgpegement with the stop 22. the port' 13 will connected with the inlet' and the port 14 with the exhaust, and, when in the port 14- wil and the port 13'with the exhaust. 7

Suitable means are mounted on the upper cylinder head 2 for actuatin the finger 25 to shiftlthe; valve'15 and t ereby reverse figement with the stop 23, connected with the inlet by means of-aradial rib 20 with a second boss 21 arranged imme .shaft 17 opp the fiow of the water. This means preferably comprises a plate 26 mounted on and movable with the motor shaft 17 and having arms 27 arranged to engage the finger 25. In the present instance this plate is segmental in form, is loosely mounted on the shaft 17 and is supported by the boss 19.

The plate 15 operatively connected to the shaft and is caused to move therewith by means of a lug 28 mounted on the late 26 at a point substantially midway etween the two arms 27 and adapted to be engaged by a part secured to the shaft 17; In the present instance this art consists of a screw 29 mounted on the s aft 17 and extending beyond each side thereof a distance suflicient to enable it to on age the lug 28 when the shaft is rotated. it will be noted that by this arrangement of the plate and the means for operatively connecting the same to the shaft, the shaft and its piston will be permitted to move through a considerable portion of their stroke before any movement is imparted to the late 26. For the purpose of quick] shiftm the valve and avoiding any possibility 0 its sto ping on a dead center, the latter rtion of t e movement of the plate 26 is imparted thereto by a. spring 30 which is arranged to actuate the same when either arm is n engagement with the finger 25 and thus positively actuate the valve.

In the resent construction the plate 26 has a radial finger 81 extendin therefrom at a point substantially midway tween the two arms 27 and one end of the-spring 30 is connected to this finger and the other end is connected to a stud 32 mounted on the upper cylinder head 2 on that side of the osit the valve stem 24 and in alincment with the shaft and the valve stem. This arrangement 'of the spring is such that, when the fin r 31 has been moved into alinement wi the stud 32 and the valve stem 24, the spring will be under its great est tension, and, consequently, as soon as the finger asses out of alinement with said member, t e contraction of the spring will tend to move the r, and, consequently, the plate, about their lpivotal' centers and toward the stud 32. he arrangement of the arm 27 relatively to the finger 31 is such that the movement of the shaft will have carried the r 31 past its dead center position, that is, the osition in alinement with the shaft 17 an the stud 32, before the arm 27 shall engage the finger 25. Consequently, a. nick movement is imparted to the yalve an the direction of-the how of the water is reversed instantly and without any possibility of the valve stopping on a dead center, with an equal water pressure on both sides of the piston. The movement of the late 26 and arms 27 is limited by the stops 3 secured to the-under side of the plate and adapted to engage the radial rib 20. Each stop is so arranged with relation to the correspondin arm 27 that it will ongage the rib 20 beore the finger 25 of the valve stem will engage the stop 22- or 23, as the case may be, thus avoiding the imparting of a severe jar to the valve, which would result if the arm 27 moved the finger positively against the stop. The finger has, however, been moved through the greater portion of its movement before the stop 33 engages to the finger and the valve will, together with the water pressure, serve to complete the movement of the valve.

The mechanism mounted on the upper cylinder head 2 may be inclosed in a housing or cap 34 which is adapted to fit about a vertically arranged flange or boss 35 carried by said cylinder head and encircling the operating parts mounted thereon. If dethe rib and the momentum imparted sired a lubricant may be placed inithe housing and the parts immer ed or partially immersed therein.

With the arts in the position shown in Fig. 1 it wilfbe noted that the water is entering the interior of the casing through the port'14 and that the piston and shaft have moved through a considerable portion of their stroke. The projection 29 on one side of the shaft is just about to engage the lug 28 on the late 26, which plate has been stationary uring the movement of the piston to its present position. movement of the flpiston will move the plate 26 a distance su cient to carry the finger 31 est its dead center position, and, when it is past this position, the spring 30 will continue the movement of the plate 26 until the stop 33 engages the rib 20, and this movement will shift the valve 15, thereby admitting the water to the interior of the The continued casing through the port 13 and reversing the direction of movement of the piston 18. It will be noted that this construction and arrangement of the motor and its 0 crating parts enable me to employ ja sing e 'valve of'a ye simple construction which may .be positive y shifted to reverse the direction owing to the character of the moving parts thereof, -no fine machine work is r uired, 'thereb enabling a ye? strong, durab e motor to manu acture at a very low cost.

While I have shown and described one embodiment of my invention it will be read ily apparent that many modifications and 1 stem extending through one of said cylm alterations of the same can be made without departing from the s irit of my invention and I, therefore, Wis it to be understood that I do not desire to be limited to the details of construction-shown and described.

Having thus fully described my invention, what I claim as new, and desire .to secure by Letters Patent, is

In a motor, a casing comprising a cylinder and cylinder heads, a shaft journaled. in said cylinder heads, a piston carried by said shaft, an abutment mounted within said oasing and ooiiperating with said piston to divi e said casing into two chambers, said abutment havin a valve chamber communicating both with a supply pipe and with anv exhaust ipe and provided with ports leading to t e respective chambers in said casin a rotary va ve mounted in said valve cham r to control said ports and having a heads, a finger mounted on said stem, a plate loosely mounted on: said shaft and having arms arranged to engage the opposite sides of saidsfinger, a In carriedby said-plate, a pro'ection arrange on said shaft to engage sai lug, a spring connected with said plate between said arms and connected with said casing in substantial alinement with said shaft and said stem, anoutwardly extending flange carried .by said cylinder head, and a cap cooperating with said flange to form a housi inclqsing the moving parts mounted on said cylinder head and adapted tooontain a lubricant.

testimon whereof, I afiix my signature in presenoe 0 two witnesses.
